We were asked to write a story in a day during the L. Ron Hubbard Presents Writers of the Future workshop (May 2011). Props were given out, and we were to use those props in conjunction with a brief conversation with a stranger on the street to formulate an idea for our stories. My prop was a rock. I wrote a story titled, "Set in Stone" that was about a discovery in a rock, on a planet threatened by rocks falling from space. The characters were as stubborn as rocks, and one of the characters was even named Rox. Plasma Frequency Magazine will publish that story.
